Dear Zdenek
Thank you very much, it works. I noticed a few more things. Not errors,
just minor things that might be documented better or handled
differently. Depending on the design philosophy.
"pvmove /dev/md127:152064-152319 /dev/md127:800000 --alloc anywhere"
fails because /dev/md127:xx seems to be interpreted as "one extent
starting at xx", I'm not sure that's what I'd guess from the man page.
"pvmove /dev/md127:152064-152319 /dev/md127:800000- --alloc anywhere"
works, but the manual page indicates that the syntax is
DestinationPhysicalVolume[:PE[-PE]...], which I would interpret as
/dev/xx:111 OR /dev/xx:111-222, but not /dev/xx:111-, that would IMHO be
DestinationPhysicalVolume[:PE[-[PE]]...].
I'd interpret /dev/md126:100 as a start of an area, since it has no
explicit bound, where as /dev/md127:100-100 I would expect for a single
extent, since there is an explicit bound. Does that make sense?
PS, how about a syntax variant where it can be /dev/md127:100+30 meaning
30 extents starting at 100? I understand it's often better to print
ranges, but maybe in some cases start+length might work better. Or
start-end+length for printing, and start[-end][+length] as input, and
exit with error if both end and length are specified and they don't
match (start+length!=length).
I'm not complaining, just suggesting enhancements. :-)
Again, thank you very much for your quick and helpful response.

Hi everyone
I'm new to the mailing list but not to LVM, until now everything was
crystal
clear and working fine. Now I'm either stuck or found a minor issue. I'm
trying to move move extents on a physical volume. Not from one
physical volume
to another.
root@myhost# pvmove /dev/md127:151808-152063 /dev/md127:152064-152319
No extents available for allocation
root@myhost#
Add --alloc anywhere
But I assume the tool could be a bit more smarter here.
It looks more or less like a bug to me.
